基于数字谱分析技术求解波耦合方程,进而计算与三波相互作用相关联的线性耦合系数和能量转移,以此开发了数据处理程序用于研究 HL-2A 装置等离子体边缘湍流中的非线性能量传递过程.介绍了算法设计和开发的主要思想.应用该程序对与带状流相关的一次放电的实验数据进行了数据处理研究.结果表明,带状流是由等离子体湍流的能量逆级联所驱动的.

Based on the Ritz method to resolve the waves-coupling equation, the data processing code was developed to investigate the non-linear energy transfer progress in plasma edge turbulence in HL-2A tokamak. The arithmetic principle and the development methods of this code were introduced. By use of this program, the discharge data with relation to zonal flow were processed and studied. The results show that zonal flow was driven by the inverse energy cascade in the plasma turbulence.
